I too had DSL with Verizon. Network worked great. Switched to FIOS with Verizon, no network!
I have even turned off the firewalls to see if that is the issue, no such luck. Even tried assigning an IP address in the Win98 network settings instead of automatic assignment (the one that the router assigns) and that works, but then I loose the connection to the internet in 98 SE. My Dell is XP connecting to a Compaq 98SE.
Any suggestions? Tried tech. They say they don't support 98SE.
